The QA team is testing a newly implemented clinical trial management (CTM) SaaS application that uses a business intelligence application for reporting.

The UAT users were instructed to use HTTP and HTTPS.

Refer to the application dataflow:

1A C The end user accesses the application through a web browser to enter and view clinical data.

2A C The CTM application server reads/writes data to/from the database server.

1B C The end user accesses the application through a web browser to run reports on clinical data.

2B C The CTM application server makes a SOAP call on a non-privileged port to the BI application server.

3B C The BI application server gets the data from the database server and presents it to the CTM application server.

When UAT users try to access the application using https://ctm.app.com or http://ctm.app.com, they get a message stating: “Browser cannot display the webpage.” The QA team has raised a ticket to troubleshoot the issue.
